Metal enamel bowl manufacturers

The core of the bowl is typically made of cold-rolled steel or cast iron. For B2B buyers, the thickness of the steel base is critical; a thickness of 0.4mm to 0.8mm is standard for lightweight camping gear, while 1.0mm or higher is preferred for premium kitchenware to prevent warping. The enamel coating must be double-fired (ground coat plus cover coat) to ensure a smooth, non-porous surface that is resistant to acid and alkali corrosion.

Since these products come into contact with food, they must comply with strict chemical migration limits. For the US market, FDA 21 CFR 175.300 and California Proposition 65 (lead and cadmium limits) are essential. For the EU, compliance with LFGB (Germany) and Regulation (EC) No 1935/2004 is required. Always request third-party lab test reports (SGS, TUV, or Intertek) to verify that the glaze is lead-free and non-toxic.

Quality enamel should have a high gloss finish without visible 'pinholes,' black spots, or uneven thickness. Perform a thermal shock test (moving the bowl from high heat to cold water) to ensure the coating does not crack. Additionally, check the rim design; bowls with a stainless steel rim or a rolled edge offer better protection against chipping compared to raw-edged designs.

Suppliers on Made-in-China.com typically offer decal printing, which is fired at high temperatures to become a permanent part of the enamel. For high-end branding, laser engraving on the metal rim or silk-screen printing on the bottom is common. Ensure the supplier uses high-temperature resistant pigments so the logo does not fade during dishwasher use or heating.

The biggest risk is chipping due to impact. Enamel is glass-like and brittle. You must mandate 5-layer corrugated export cartons and individual bubble wrap or egg-crate dividers. Request a drop test report (ISTA 1A) from the supplier before the bulk shipment leaves the factory to minimize transit damage.

Standard MOQs for custom colors usually range from 1,000 to 3,000 pieces. To lower costs, ask for 'stock colors' (usually white, cream, or navy) which may allow for MOQs as low as 500 pieces. When negotiating, focus on the total weight of the metal base, as fluctuations in steel prices significantly impact the unit cost.

Metal enamel bowls are heavy and relatively low-value per cubic meter. For large orders, Sea Freight (FCL or LCL) is the only economically feasible method. If shipping to the US or Europe, ensure the supplier provides a Certificate of Origin to potentially benefit from trade agreements and clarify the HS Code (typically 7323.94) to accurately calculate import duties.

Always verify the supplier's Business License and Export Qualification on the platform. Prioritize Audited Suppliers on Made-in-China.com, as they have undergone on-site inspections. For the first order, utilize a third-party pre-shipment inspection (PSI) to check for coating defects and quantity accuracy before paying the final 70% balance.
